Have tried different bootloader setup, with different outcomes...
ATM. I get this error/hang - "Unknown CPU: family = 0x17, model = 0x8, Stepping = 0x2"
Have search google, and can see that the threads ppl. are getting this, is when they look at "About this mac", I haven't yet installed the OSX.

Now I want to add vector graphics support in Clover. See rev 4560 and later.
It is not working yet but designers may begin to create Vector Themes.
It supposed to consist of SVG elements and has design size. It will be rendered to any screen size scaled from design size.

What application in macOS can create SVG graphics?
Inkscape is not working in macOS 10.11+. Pity.
LibreOffice Draw works with SVG but buggy.
Boxy SVG cost 10$ but looks good enough. It creates the best in simplicity files and have more then enough features.
Illustrator is good but expensive.

How to improve SVG file?
Clover has restricted support for SVG. It is your job to make compatible file and as small as possible to speedup rendering.
Some helps:
Help:Inkscape – From invalid to valid SVG Inkscape files
From invalid to valid SVG Adobe Illustrator files
From invalid to valid SVG files of other editors: BKchem, ChemDraw and CorelDRAW
Help:Illustrator – Assistance with creating and saving SVG images in Adobe Illustrator that will pass W3C validation
User:Quibik/Cleaning up SVG files manually
Later I will write own instructions specific to Clover abilities.

How to create SVG fonts?
You can google to find ready-to-use SVG fonts. I found some problems with too beaty fonts: slow rendering and overflow crash. Be careful.
You can get ttf or otf fonts and convert them into svg by using online WEB services. Not a problem to google.
But then I want to find a way to simplify the font to reduce a size and speedup rendering.
You can create own font by FontForge It is opensource and available for Windows, Mac and GNU+Linux. It creates otf font which you can convert to svg font.

Just so you all know I actually have done something. I have pushed the source to both my github and to sourceforge, please commit to the experimental branch and I will merge it into the stable branch once it is safe. Also, nothing meaningful happens yet so don't get too excited. Only the Visual studio build works right now. I haven't set up the Xcode or Makefile builds yet, I'm trying to do them now.
